I am seeking advice here from any mumsnetter with older boys. My four and a half year old is (and has been for sometime) obsessed with pretend guns -- sticks, lego, old plastic bottles ... you name it, it's a gun. He 'shoots' complete strangers in the street, his sister, friends, aliens hiding in the bushes, anyone. All with wild yells of delight. Sticks are another passion of his. He collects them, carries them around with him, stores them. Loves them. And he also quite enjoys kicking his sister, and hitting out at 'annoying' other children, or me. (Sometimes he seems genuinely angry when he does this. At other times I feel he is just acting.) Are there two things going on here: a natural tendency to pretend-weapon play on the one hand and normal childhood frustration/aggression that he needs to learn how to handle on the other? Or does one feed into the other? He has an older sister (6; who doesn't fight back often) and a younger brother (6 months; to whom he is, incidentally, never anything but perfectly gentle and kind). With my DD, we had the aggression but not the weapon play and so we dealt with the anger and all is (mostly) well. But I'm not sure how to handle this male impulse towards play fighting. I find myself getting embarrassed in public when he gives full vent to his imagination ... but should I just relax and let him play out his natural tendencies while preventing him from actually fighting when he gets cross? (My mother thinks I should snatch any weapon from him and dash it to the ground with a lecture about wars and killing people. But then she had two girls ...) Views please.
